Understanding Pressure Washer Terminology
When it comes to pressure washing in St. Louis, understanding the key technical terms is essential for selecting the appropriate equipment and techniques for the job. The primary factors to consider are pounds per square inch (PSI), which measures the water pressure, and gallons per minute (GPM), which indicates the water flow rate. These two metrics together determine the cleaning units (CU) of a pressure washer, which is the product of PSI and GPM.
Higher PSI indicates stronger water pressure, which is necessary for removing tougher stains or coatings. However, excessively high PSI can potentially damage delicate surfaces. Similarly, higher GPM translates to faster cleaning, as more water is being used to cover a larger area. The ideal balance of PSI and GPM will depend on the specific cleaning task at hand.
In addition to water pressure and flow, temperature is another important factor. Some professional-grade pressure washers in St. Louis are equipped to handle hot or warm water, which can significantly improve the cleaning efficiency for certain applications, such as removing grease or oil-based contaminants.
Choosing the Right Pressure Washer Nozzle
The type of pressure washer nozzle you select is crucial for the success of your cleaning project. Different nozzles are designed for specific purposes, and using the wrong nozzle can lead to suboptimal results or even damage to the surface being cleaned. Let’s explore the common nozzle types and their recommended uses in the St. Louis area:
Red Nozzle (0-degree)
The red nozzle produces a highly concentrated, powerful stream of water that is ideal for removing stubborn stains or coatings from concrete, metal, or masonry surfaces. However, it is not recommended for use on wood, siding, or other delicate materials, as the high-pressure stream can potentially cause damage.
Yellow Nozzle (15-degree)
The yellow nozzle creates a wider, fan-shaped spray pattern that is well-suited for surface preparation, such as removing dirt, mold, mildew, or old paint from siding, fences, or driveways. This nozzle can be used on a variety of surfaces, including concrete, wood, and metal.
Green Nozzle (25-degree)
The green nozzle produces a broad, low-pressure spray that is ideal for sweeping away dirt, mud, or leaves from larger areas like driveways, sidewalks, or decks. This nozzle is a good choice for gentle cleaning of surfaces that may be prone to damage from higher-pressure water.
Black Nozzle (low-pressure detergent)
The black nozzle is designed for applying cleaning solutions or detergents to the surface before rinsing. It delivers a low-pressure, high-volume spray that helps the cleaning agents penetrate and loosen dirt or grime effectively.
Rotating Nozzle
The rotating nozzle features multiple adjustable nozzles that produce a circular, high-pressure spray pattern. This nozzle can significantly reduce cleaning time by providing extra cleaning power, and it is particularly useful for reaching areas that are difficult to access, such as second-story walls or gutters.
When selecting a nozzle for your pressure washing project in St. Louis, it’s essential to consider the specific surface material, the level of soiling or staining, and the accessibility of the area. Consulting with a professional pressure washing service can also help ensure you choose the most appropriate nozzle for your needs.

Pressure washing contractors must ensure that all detergents, oils, and other contaminants are properly contained and disposed of, in accordance with local environmental protection laws. Improper disposal of wastewater can result in significant penalties.

This includes items such as safety glasses, gloves, and protective clothing to minimize the risk of injury from high-pressure water or chemical exposure.

This includes following the manufacturer’s instructions for the pressure washer, using the appropriate nozzle for the job, and taking precautions to protect nearby plants, windows, or other sensitive areas.
It’s worth noting that in some cases, homeowners may be required to obtain a permit for pressure washing activities, particularly if the project involves the use of chemicals or the discharge of wastewater. Consulting with the local authorities can help ensure compliance with all relevant regulations.
